Lindsey=l
Logan=h
h=l+2
(h-5)+(l-5)=30
h-5+l-5=30
h+l-10=30
h+l=40
l+l+2=40
2l+2=40
2l=38
l=19
h=21
So Lindsey is 19

Hope this helps :)

X is 2 more than y
x=2+y

5 years ago (x-5 and y-5)
sum is 30
x-5+y-5=30
x+y-10=30

x=2+y
sub 2+y for x
2+y+y-10=30
2y-8=30
add 8 to both sides
2y=38
divide both sides by 2
y=19

Lindsey is 19

What are the X and Y intercepts of y= -2(x-4)2 +3
kari74 [83]

Answer: x-intercepts are ( 2.775,0) and (5.225,0)

And y-intercept is (0,-29)

Step-by-step explanation:

Here the given equation is,

y = -2(x-4)^2+3

For x-intercept, y = 0,

Put y = 0 in the above equation of parabola,

We get, -2(x-4)^2 + 3 = 0

-2(x^2+16+8x) + 3 = 0

-2x^2-32-16x + 3 = 0

-2x^2-16x -29 = 0

By solving this equation,

We get, x = 2.775 or x = 5.225

Therefore, x-intercept of the given parabola are (2.775, 0) and (5.225,0)

Now, for y-intercept, x = 0

By putting x = 0 in the given equation of parabola,

We get, y = -29

Thus, y-intercept of the given parabola = (0,-29)
